PATNT FFE JOSEPH J. STEVENS, OF DALTN, KANSAS ATTACHMENT FOR LISTERS iApplication filed July 17,

By wavy of explanation, it may be stated that listers as at presentconstructed drop the seed at the bottom of the furrow, in a place in thesoil which is hard and cold. rdinarily, the seed is planted too deeply,and in dry weather the moisture evaporatcs. In case a rainy seasonintervenes, before the seed has come up, the seed is likely to be keptwet and cold too long, since the sub-soil is slow to let the water soakaway, the result being that if the plant is not killed, it is stunted,and if the seed has not sprouted, the chances are that it will rot, areplanting being necessary.

The foregoing being understood, it may be stated that it is the objectof the present invention to provide a novel lister attachment rsoconstructed that the seed will be planted in a prepared bed in thefurrow, at a much reduced depth.

lt is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to whichthe presentinvention appertains.

`With the foregoing and other objects in. view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction'hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of the invention herein disclosed, within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure l shows in side elevation, a listermechanism in which the device forming'the subject matter of thisapplication has kbeen embodied g Figure 2 is a top plan.

rlhe device forming the subject mattery of this application may beembodied in standard machines of many di erent sorts, but, by way ofillustration, there is shown in the drawings a machine comprising a mainframe l to which beams 2 are connected, as shown at 3, the beamscarrying the furrow openers 2G. Listers 21 are carried .by the frame l,and are disposed to the rear and slightly at one side of the furrowopeners 20, as is common.

Axles 4 are provided, ground wheels 5 be- 1930. Serial No. 463,619.

ing journaled on the axles. rEhe axles i have cranks 6, mounted at 7 torock on the beams 2. Segments 8' are mounted on the beams 2. Levers 9are secured to the inner ends of the cranks 6, and have latch mechanismsl adapted to cooperate with the segments 8, to form a raising andlowering mechanism well understood by those skilled in the art.

Ferllizcr distributors ll are mounted on the main frame l and dischargethrough shoes l2 disposed behind the furrow openers 2O and in advance ofthe listers 2l. rlhe fertilizer distributors l1 are operated by atransverse shaft lll.

rlhe numeral l marks a substantially vertical casing in the upper end ofwhich a shaft 16 is ournaled. A chain and sprocket drive 17, locatedwithin the casing l5, connects one of the ground wheels operatively withthe shaft i6. A substantially horizontal casing 18 is mounted on theshafts la and 16 and within the casing 18 is clsposed a chain andsprocket drive 19 which connects the shaft 16 with the shaft la thatoperates the fertilizer distr'butors ll. Y

Seeders 22 are mounted on the rear portion of the. main frame l anddischarge through telescopic tubes 23 into shoes 24 disposed to the rearof the listers 2l. rlhe lower ends of braces 25 are connected to theshoes 24, the upper ends of the braces being adjustably mounted at 2G onsecond braces 29 mounted on the frame l, to enable the shoes 24 to beadjust-ed vertically. Links 2? are pivoted to the forward ends of theslices 24:, and are connected by a pivot bolt 2S with the beam 2. rEhebraces 29 extend between the bolt 28 and the rear portion of the mainframe l. Y

rlhe seeders 22 are operated by a transverse shaft 30 and this shaft isdriven from the shaft 14 (which may be called a second shaft) by a chainand sprocket drive 3l, located within a second casing 32 carried by theshafts lll and 30. i

Y Auxiliary frames 33 are mouned to swing vertically on the pivotelements 28 and extend rearwardly beyond the'back endof the main framel. The auxiliary frames 33 are connected by a cross rod 34. Upwardlyextendral 'lill ed links are connected at their rear ends to the crossrods 34, the forward ends of the links being pivoted to rearwardlyextended arms 36A on a shaft 37 mounted to rock on the frame 1. The shat 3'? has an upstanding arm 38 to which is pivoted a forwardly extendedconnecting rod 39. 'lf he forward end of the connectingl rod 39 ispivoted to a lever 40 mounted on the frame 1, the lever having a latchmechanism 41 adapted to cooperate with a segment 42 on the frame 1.

Packer wheels 43 are mounted to rotate in the auxiliary frames 33 andhave concaved treads which are open, as shown at 44 on bot-h sides ofthe median plane of each wheel 43. Scrapers 45 are adjustably mounted at46 on the auxiliary f 1ames and ci Ue the packer wheels 43, to cleanthem from t irt.

In practical operation, as the machine moves forwardly, the member QGopens the furrow. The fertilizer is dropped through the shoes 12 intothe furrows although a fertilizer distributor may or may not be used, asis found expedient. 'he listers Q1 lill the furrow partially, and afforda properly prepared seed bed. The seed is dropped from the shoes 24 intothe furrow at a comparaH tively shallow depth. Finally, the packerwheels 43 pass over the soil and, owing; to the conca-ved shape of thetrack of the packer wheels, the seed is covered. Owing` to the fact thatthe packer wheels are open at their median plane, as shown at 44, thesoil immediately above the seed is not packed down unduly. rlhe seeddeposited on earth that has been properly prepared to form a bed, andthe seed is covered by dirt not so firmly compacted but that the sproutscan find their way upwardly without difficulty through the dirt. Thedevice avoids all of the disadvantages incident to planting seeds, itbeing observed that, as shown in Figure 1, the sh oe 24 that depositsthe seed does not extend downwardly so far into the ground as does thefurrow opener 20.

Owing to the construction embodied in the device, the lister can be rundeeper, by several inches, than .is custon'iary, thereby breaking theway for better seed bed, prepared asv hereinbefore described.Fertilizers, lime and the like, can be dropped down on the bottom of thefurrow, where such material will do the most good, and the seed rootswill go down to it, The seed which is planted will be in moist dirt, andthe packer wheels 43, being open upon their treads will leave the seedsin fine shape to make a start.

The drive is simple; one of the ground wheels 5 ope-rates the chain andsprocket drive 16, rotation *being imparted to the shaft 16, the chainand sprocket drive 19 operating the shaft 14 of the fertilizer distributor 11 (which may be called a third shaft), and motion beingtransmitted from the shaft 14, by Way of the chain and sprocket drive31, to the shaft 40 which operates the seeders 22.

Through the instrumentality of the lever 40, the auxiliary fames 33 andthe packer wheels 43 may be raised and lowered by atrain of partsincluding` the connecting rod 39, the arm 38, the shaft 37, the arms 36,and the links Having thus described the invention, what is claimed is:

1. An agricultural implement embodying a wheel-mounted main frame, afurrow opener carried thereby, a seeder on the main frame and includinga shoe mounted for raisinr and lowering and located in the wake of thefurrow opener, an auxiliary frame, a packer carried by the auxiliaryframe and disposed behind the shoe, a downwardly and forwardly inclinedbrace having its rear end connected to the main frame, another bracehaving its lower end connected to the shoe, means for connectingl theupper end of said other brace, adjustably to the lirst-specilied brace,a forwardly extended link having its rear end connected to the forwardportion of the shoe, and a pivot element connecting the auxiliary f ameto a part of the furrow opener', the forward end of the link and theforward end of the first-specified brace being mounted on the pivotelement.

2. In an agricultural implement embodying a main frame carrying a seederhaving a shaft, a forward axle, a ground wheel journaled on the axle,means for raising;` and lowering the axle with respect to the frame, anda furrow opener carried by the main frame and located in advance of theseeder: mechanism whereby the shaft of the seeder is rotated from theground wheel, said mechanism comprising a substantially vertical cas inghaving` its lower end mounted to swing on the axle, a second shaftjournaled in. the upper end of the casing', a chain and sprocket drivein the casing and connecting the ground wheel with the second sha-ft, athird shaft journaled on the frame between the casing and the seedershaft, a second and substantially horizontal casing mounted for verticalswingingr movement on the second and third shafts, a chain and sprocketdrive in the second casing and connectingi the second and third shafts,and means for driving):y the seeder shaft from the third shaft.
